Norris, McQueen & Cutler argue that there is no need for feedback in word recognition. Given the accumulating evidence in favor of feedback as a general mechanism in the brain, I will question the utility of a model that is at odds with such a general principle.

Much has been written on the relative merits of different readings of Wittgenstein's Tractatus Logico-Philosophicus. The recent renewal of the debate has almost exclusively been concerned with variants of the ineffabilist (metaphysical) reading of TL-P - notable such readings have been advanced by Elizabeth Anscombe, P. M. S. Hacker and H. O. Mounce - and the recently advanced variants of therapeutic (resolute) readings - notable advocates of which are James Conant, Cora Diamond, Juliet Floyd and Michael Kremer. During this debate, (...) there have been a number of writers who have tried to develop a third way, incorporating what they see as insights and avoiding what they see as flaws in both the ineffabilist and resolute readings. The most prominent advocates of these elucidatory readings of TL-P are Dan Hutto (2003) and Marie McGinn (1999). In this paper we subject Hutto's and McGinn's readings of TL-P to critical scrutiny. We find that in seeking to occupy the middle ground they ultimately find themselves committed to (and in the process commit Wittgenstein to) the very ineffabilism they (and Wittgenstein) are seeking to overcome.

This paper investigates the magnet as a classic “boundary object” of modern technoscientific culture. Equally at home in the nursery, dynamo, measuring instrument and navigational compass, its capricious performance nevertheless persistently eluded the powers of nineteenth century electromagnetic expertise in pursuit of the completely “permanent” magnet. Instead the untamed magnet’s resilient secularity required its makers to draw upon ancient techniques of chemical manipulation, heat treatment and maturation to render it eventually sufficiently stable in behaviour for orderly use in modern engineering. (...) The precise methods for accomplishing this quasi-permanence were typically protected by trade secrecy – until that is Marie Sklodowska Curie’s first research publication opened up this topic for rigorous comparative research in 1898. Nevertheless, over the next quarter century her work in this field was gradually eclipsed by heavily gendered citation practices, just as the futility of attempting to accomplish complete permanency in magnets was eventually established by Sydney Evershed in the 1920s.

The aim of this paper is to defend the position that aesthetics and ethics in sport are not two separate domains or aspects. In sport, the aesthetic and the ethical both arise from sport’s attractiveness or from the pleasure sport offers to its activists and consumers. To think about sport philosophically, we should find a link and a principle beyond this division as a source of both the aesthetic and the ethical in sport. The philosophy and philosophical sociology of Jean- (...) class='Hi'>Marie Guyau is presented as a response to this problem. Two points of fundamental importance are considered critically here: his criticism of any reductionism, and life or the idea of life as key principle of a philosophical system which puts ethics and aesthetics together.

A history of the Atomic Bomb from Marie Curie to Hiroshima. “I am become Death, the destroyer of worlds” — Oppenheimer quoting the Bhagavad Gita after witnessing the successful demonstration of the atom bomb. The bomb, which killed an estimated 140,000 civilians in Hiroshima and destroyed the countryside for miles around, was one of the defining moments in world history. That mushroom cloud cast a terrifying shadow over the contemporary world and continues to do so today. But how could (...) this have happened? What led to the creation of such a weapon of mass destruction? From the moment scientists contemplated the destructive potential of splitting the atom, the role of science changed. Ethical and moral dilemmas faced all those who realized the implications of their research. Before the Fall-Out charts the chain of events from Marie Curie’s scientific breakthrough through the many colourful characters such as Einstein, Robert Oppenheimer and Lord Rutherford, whose discoveries contributed to the bomb. The story of the atomic bomb spans 50 years of prolific scientific innovation, turbulent politics, foreign affairs and world-changing history. Through personal stories of exile, indecision and soul-searching, to charges of collaboration, spying and deceit, Diana Preston presents the human side of an unstoppable programme with a lethal outcome.
